It's tender on one side. It's not particularly lumpy, or dippled, or has a rash, there's no change to the nipple and it doesn't look any different. But it's definitely tender.
I thought it was a combination of my period and a new bra. I turned over in bed last night, from laying on that side to the other, and it really hurt as it moved.
I'm going to have to see a doctor aren't I? Any change to a boob has to be checked out doesn't it?
